Be thirsty for knowledge. Blockchain technology and crypto trade are new spheres when compared to mainstream industries and much is in development right now. Knowing more will increase your success chances, build up your trading portfolio but also the quality of analysis you do on daily basis. Investigate things that have nothing to do with trading but can help you understand the market better.
Each day there are exciting discoveries that can change the face of the crypto world drastically. Understanding them will help you develop your own strategy, design more effective analysis, and generally improve your trading skills.
I was going to say that these things doesnt matter (the blockchain, industries etc) but when you stated that they dont matter but having their knowledge can influence our trades then I realised yes this is the thing one must know. Off course, while trading all we need to know is about the coin's idea and project behind it and how it is getting processed over the time. Depending upon that crypto currencies get investors engaged more and more as the days pass and thus they grow in the value every time. I guess having the additional knowledge about blockchain and how the world is reacting to it is also important. This ensures us that how the whole market is going to react with it and how it will affect your coin or projects in that environment. So yeah it matters, be thirsty !
